The Low Mass X-ray Binary (LMXB) in NGC 6652 is one of about
10 bright X-ray sources to have been discovered in Globular
Clusters. This LMXB was securely discovered in the ROSAT
All-Sky Survey, but is probably identical to the HEAO-1
source whose relatively large error box contained NGC 6652.
More recently, a Type I X-ray burst from this LMXB was
detected in BeppoSAX WFC data.

Here we report on a serendipitous ASCA observation of this
Globular Cluster LMXB, including the detection of a
long-duration (>200 s) Type I burst. Our quiescent
(non-bursting) spectrum is the best yet obtained for this
source, which apparently was at its brightest level recorded
to date. We present spectral and timing properties of the
quiescent data as well as the spectral evolution of the
burst. We present the evidence for a spectral cooling during
the burst, which probably did not reach the Eddington
luminosity for a 1.4 M_ødot neutron star. We will discuss
these results in the context of Globular Cluster LMXBs.
